The protein encoded by this gene is a member of the
immunophilin protein family, which play a role in immunoregulation and basic cellular processes involving
protein folding and trafficking. This encoded protein is a
cis-trans prolyl isomerase that binds the immunosuppressants FK506 and
rapamycin. It has a higher affinity for rapamycin than for FK506 and thus may be an important target molecule for immunosuppression by rapamycin. == Interactions ==
